GAS-FILTER.

Specification of Letters Patent.

Patented Nov. 8, 1910.

Application filed April 6, 1910. Serial No. 553,780.

To all whom it may concern;

Be it known that I, Gnonen S. LINN, a citizen of the United States,residing at Santav Barbara, in the county of Santa Barbara and State ofCalifornia, have invented certain new and useful Improvements inGas-Filters, of which the following is a specification.

This invention relates to devices for filtering gas, and has for itsobject to provide such a device which is adaptable for use in purifyingeither acetylene or illuminating gas formed from coal.

It has for its objectto provide such a device which is adapted toseparate liquid from gas as well as to remove particles of mattersuspended therein.

An important object of the invention is to provide a separator arrangedto accumulate liquid separated from the gas in such a way that it may bedrawn off while the device is in use without impairing its operation.

A further important object is to provide a novel form of strainer deviceso constructed as to allow the escape of liquid collected thereby.

A further object is to provide such a device which will occupy a minimumamount of space, and may be applied to use upon motor vehicles equippedwith acetylene generators, or may be incorporated in gas lightingsystems of houses, requiring only to be made in the proper sizes forthese various uses.

Other objects and advantages will be apparent from the followingdescription, and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimwithout departing from the spirit of the invention.

In the drawings: Figure 1 is a vertical longitudinal sectional viewthrough the device, Fig. 2 is a horizontal sectional view centrally ofthe device, looking upwardly, Fig. 3 is a cross section on the line 55of Fig. 1, looking toward the outlet end, the outer casing being partlybroken away, Fig. 4 is a longitudinal sectional view of a modificationof the strainer casing.

Referring to the drawings, there is shown a cylindrical receptacle 10disposed on a horizontal axis and having the heads 11 and 12 at oppositeends, rovided with intake and exit tubes 14 an 13 respectively, and

provided with a suitable drain cock 15 at its lower side, as shown. Theinlet pipe may be dlsposed at a point in the head. 12, but the outletpipe 13 is preferably disposed adja-- cent the upper side of the device,and the adjacent head 12 is made detachable in any suitable manner,shown beingthreaded upon the receptacle 10. Carried by the head 12 thereis a suitable strainer casing 16, scgmental in cross section and havingan areaatc upper wall 17 and disposed closely adj acent the cylindricalwall of the receptacle 10 and concentric therewith and a connected planelower wall 18. One end of this strainer casing is secured to the head12, circumscribing the point of entrance of the inlet pipe 14:, andcarried within the casing a spaced distance from the head 12, there is asuitable screen 19, and hingedly secured to the opposite end edge of thefloor 18 of the strainer casing, there is a similar screen 20 conformingto the shape of the casing and adapted to fit snugly against the arcuateupper wall thereof. The strainer casing projects over only a portion ofthe length of the casing 10, and is filled with a suitable fibrous orpermeable material 21 such as cotton or wool the screen 20 being closedthereover, as shown. The floor 18 of the strainer casing is perforated,and when in use any moisture accumulating in the material 21 willnaturally gravitate to the lower portion thereof and escape through theopenings in the floor 18, being collected in the large space in thereceptacle beneath the strainer casing.

In use, the intake tube 14 is connected in any suitable manner with asource of supply, while gas is conducted from the device through thetube 13 to the point of use by any suitable piping system. When it isdesired to drain the casing, whether the device is in use or not, thecock 15 may be opened, and if the gas is being supplied under pressurethe escape ofany fluid in the receptacle will be more rapidlyaccomplished. When the material 21 in the strainer casing has becomefouled, and it is desired to renew the same, the head 12 supporting thecasing is removed, together with the casing the strainer or screen 20 isopened outwardly, and the material 21 removed from therein. Freshmaterial is introduced, and the reverse operation followed in replacingthe casing.

It will be seen from the foregoing that sectional View of a modifiedform of the device in which the strainer casing is enlarged at its innerend, the floor 18 being inclined downwardly from. the point. of supporton the head 12, this construction facilitating the drainage of moisturecollected to the lower sides of the strainer casing for escapetherefrom; the permeable material 21 adjacent the inner end of thecasing may become saturated with moisture to a greater extent than thatnearer the escape openings, offering more resistance to passage of thegas, and causing such moisture to be drawn inward in the casing. Byenlarging the casing toward its inner end, a larger straining surface ispresented Whereby tendency of the moisture to be pressed inward isgreatly reduced and escape facilitated, as will be readily appreciated.

What is claimed is:

In a device of the class described, the combination with a cylindricalcasing disposed on a horizontal axis and having drain openings at itslower side, of closing heads at opposite ends thereof, inlet. and outletpipes leading respectively from the heads, one of said heads having uponthe inner side thereof circumscribing the outlet pipe a transverselysegmental strainer casing having a plane floor and arcuate upper wallconcentric with the wall of the cy]indrical casing, the inner end ofsaid strainer casing being disposed intermediately of the cylindricalreceptacle, a screen member carried across said strainer casing spacedfrom the supporting heads, a second screen hinged to the opposite end ofthe strainer casing and adapted to close said ends, said plane floorhaving perforations therethrough and permeable material carried in thecasing for collection of moisture in gases passing therethrough fordrainage by gravity through the openings in said floor.

In testimony whereof I afiix my signature, in presence of two Witnesses.
